What hardware do you use?

A year-old MacBook Air. When I'm in my home office, I dock it with the mother ship (Apple Cinema display, keyboard, Magic Mouse, and external hard drive), but most days I'm nomadic, so what's on my desk is less important than what's in my shoulder bag.

Contents of shoulder bag:

1) MacBook Air. It's light, and the battery lasts all day. I often don't even carry a power cord.

5) Moleskine sketchbook, for cafés, airports, restaurants, and whenever I have a few minutes downtime. I always take it with me, because the days I'm sure I won't want it, I'm wrong.

6) A thinner, red Moleskine notebook for notes and rough drafts. I don't use looseleaf sheets, because they end up getting lost. The notebook lasts longer than you'd think -- I go through two or three a year -- and becomes a kind of journal.

My first-gen iPad gets a lot of use around the house, but I'll only take it with me if I have a reason, like a screenplay PDF to read or an iOS app to playtest.

Home office setup includes an iMac with USB hub connected to various devices, including a three-year-old Okidata 5800 color laser printer that used to be able to print wirelessly on our Apple Airport Extreme network, but the software hasn't kept up; a ScanSnap scanner; and assorted 1TB and 2TB external hard drives containing several tons' worth of paper, CDs, DVDs, VHS, DAT, mini-DV, Hi-8, celluloid, Exabyte, 5.25" floppy disks, and other last-century storage media.

The fact that .pdf has replaced paper for 99% of what I do makes not having a networkable printer less of an inconvenience than it might be.

And what software?

Evernote for notes, journaling, and quickie writing like emails and blog posts. I also use it to transcribe what I've scribbled in my red Moleskine. When the notebook fills up, I shelve it and start a new one. Notebooks aren't great for searchability, but they're interesting to browse through years later.

Things for getting things done. Although the Allenic ideal of an empty in-box eludes me, I do try to be vigilant about consistently moving action items out of Mail, iCal, Evernote and Moleskine and into Things, so they're all in one place.

What would be your dream setup?

I still have the Moleskine sketchbook -- except they've changed the paper, so it's more of a true white and doesn't repel watercolor.

One iPad-sized tablet combining the functions of all the Macs, cameras, iPhone, Kindle, wireless networks and hard drives. The tablet screen can switch from glowing to e-ink mode, and doubles as a scanner, so I can scan pages anytime.

An iPhone-sized version that's identical, only the screen is smaller. They're always synced, so whichever one I take with me, it has all the same stuff on it.

And a one-touch off button, so I can toss those amazing gadgets in a drawer and forget they exist, at least for a couple of hours.
